    Warrawee Granny Flats Built Around Your Property

    Warrawee features predominantly brick homes from the 1960s through to the 1980s, set on generous blocks typically ranging from 800 to 1,200 square metres. These established properties offer ample rear and side yard space, making them ideal candidates for granny flat additions. The level to gently sloping blocks common throughout the suburb allow for straightforward construction without significant excavation costs.

    We service Warrawee, Turramurra, Wahroonga, Hornsby, Pymble and North Turramurra with granny flats tailored to Upper North Shore properties. Our team has extensive experience navigating Ku-ring-gai Council requirements and designing compliant secondary dwellings that suit local planning controls. Whether you need a compact studio or a spacious two bedroom granny flat, we deliver designs that maximise your block’s potential.

    The Warrawee property market remains strong with median house prices consistently above $2.5 million, driving demand for affordable rental accommodation in the area. Self contained granny flats in the Upper North Shore command weekly rents of $600 to $750, providing excellent returns for property owners. With interest rates stabilising and strong rental demand from families and professionals, now is an ideal time to add a secondary dwelling.
